<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: YunQiang Su (wzssyqa) <details> <summary>Changes</summary> TargetInfo has HasUnalignedAccess support now. For MIPSr6, we should set it according strict-align. For pre-R6, we always set strict-align and HasUnalignedAccess to false. --- Full diff: https://github.com/llvm/llvm-project/pull/87256.diff 1 Files Affected: - (modified) clang/lib/Basic/Targets/Mips.h (+6) ``````````diff diff --git a/clang/lib/Basic/Targets/Mips.h b/clang/lib/Basic/Targets/Mips.h index c9dcf434c93b0b..f5ce1bc735a700 100644 --- a/clang/lib/Basic/Targets/Mips.h +++ b/clang/lib/Basic/Targets/Mips.h @@ -318,6 +318,7 @@ class LLVM_LIBRARY_VISIBILITY MipsTargetInfo : public TargetInfo { FPMode = isFP64Default() ?
